Wei Han was forced to transmigrate to another world. Since he was no hero, the only way he could get home was to use his ability to return from death and assassinate the Demon King over and over again.
After the seventy-third attempt, Wei Han succeeded. But with his dying breath, the Demon King asked him in a Hebei accent:
"Have the Japanese devils been driven out yet?"
He had been looking after hundreds of thousands of people who had escaped the mines, making sure they had enough to eat and warm clothes to wear.
Yet the kingdom called him the Demon King, and for its own gain kept summoning heroes to kill him.
So Wei Han closed the door to going home:
"He did nothing wrong. The whole world is at fault."
"I'll carry this flag now."
"Demon King? No. From today on, I'm a revolutionary!"
"Demon King's Army? From today on, we're the Revolutionary Army!"
He wasn't a hero. The kingdom didn't need him, and neither did the will of the world.
But the poor working people needed a flag to rally behind.
He had died seventy-three times already, and didn't mind dying a few more.
